Check out this nice picture of asterina starfish eating my SPS coral today. Little buggers. I am rather found of that coral. It has beautiful coloration and great polyp extension. I just don't get it. Although I have had asterina starfish in my aquarium for years, I still am not sure if they are opportunistic or predatory. In this case, I believe they are predatory. That coral has been booming for some time now and rather bullet-proof. Yet last week, I glanced over and smack in the middle was a bone white branch with a starfish on it. The picture below is from tonight and on the lower left branch, there are two of them munching away. Interestingly, the tip of the branch they are on is still green, they appear to be working their way up from the base. It was 9 years ago, when I posted - these pics - when I had some going over montipora. Sigh. Someday I will find some big bongo...

Recently on the T5 board I reached out about actinic bulb recommendations as my bulbs were cooked and discontinued. The general consensus was that I couldn't go wrong with a couple German brands and also to go with 460nm to really pop. Having read this, 3reef sponsor Hamilton Technology asked if I would like to try out their German-made 460nm T5 HO bulbs and I gladly accepted. The timing was right. Read on for a little review.


Hamilton Technology has been around the aquarium scene for a long time. I am pretty sure in the pre-internet days, I was seeing their ads in FAMA magazine. That had to be over 20 years ago. These guys are wise in their old age and know a thing or two. It shows in modest ways like the reflector on their Cayman Sun HQI pendants or in this case, with the packaging care taken on shipping their 460nm T5 HO bulbs my way. Check this out:...
